| What are exocrine secretions? | 1. Provides physical protection 2.conrols permeability 3.Provide sensation 4.produce Specialized Secretions |
| Where are epithelia found? | It covers the skin,it linea internal passageway that communicate with the outside such as the digestive, repiratory, reproductive, and urinary, tracts |
| small, fingerlike extensions of the exposed cell of an epithelial cell | microvilli |
| The matrix of cartilage consists of a firm gel and cells called | chondrocytes |
| What are endocrine excretions? | They are secrteions released into surrounding tissues and blood. These secretions are hormones that producesd in specific organs |
| are layers of cells that cover internal or external surfaces | epithelia |
| formed by the fusion of the outer layers of the cell membranes; it prevents the passage of water and solute between cells | tight junctions |
| a collection of cells | tissues |
| this includes epithelia and glands | epitheilal tissue |
| cell membranes of two cellls are locked together by intercellular cement and by membrane proteins | desmosomes |
| two cells are held toghether by embedded membrane proteins, they are channel proteins that form a narrow passageway that lets small molecules and ions pass from cell to cell | gap junctions |
| the study of tissues | histology |
| What are some types of exocrine glands? | They secretions dischargedonto the surfacde of epithelium. Examples:Milk of mammary glands, perspiration on the skin, enzymes entering digestive tract |
| It is composed of secreting cells derived from epithelia | glands |
| What are the functions of epithelia? (PSP'S) | |
